A kind of moulded coal being made using the moulded coal raw material.
The specific embodiment provided according to the present invention, the invention discloses following technical effects:
By the invention it is possible to realize a kind of moulded coal raw material and moulded coal, in an implementation mode, which includes following weight
The component of part: coal dust 50-60 parts by weight；Coal slime 40-50 parts by weight；Lime powder or calcium carbide dust 8-12 parts by weight；Wherein, institute
State the coal slime that coal slime is coal washing plant coal washing process output；The coal dust, coal slime and lime powder or calcium carbide dust respectively contain
The maximum gauge of particle monomer be no more than 5 millimeters.Moulded coal raw material provided by the present application replaces traditional moulded coal system using coal slime
Make the clay used, while guaranteeing that the moulded coal hardness being made reaches requirement, the calorific value of moulded coal can be made to mention significantly
It rises, while solving the problems, such as that current coal slime cannot achieve and recycling industrial production.The raw material has transport storage easy to use
Characteristic, have many advantages, such as environment protection smokeless using the moulded coal that the raw material is made, calorific value is high.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
Specific embodiment
The following is a clear and complete description of the technical scheme in the embodiments of the invention, it is clear that described embodiment
Only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, the common skill in this field
Art personnel every other embodiment obtained, shall fall within the protection scope of the present invention.
The present invention provides a kind of moulded coal raw material, which includes the component of following parts by weight:
Coal dust 50-60 parts by weight；
Coal slime 40-50 parts by weight；
Lime powder or calcium carbide dust 8-12 parts by weight；
Wherein, the coal slime is the coal slime of coal washing plant coal washing process output；The coal dust, coal slime and lime powder or calcium carbide powder
The maximum gauge for the particle monomer that dirt respectively contains is no more than 5 millimeters.
Further, the coal dust is the mixture of single kind coal dust or several type coal dusts.The coal slime is through drying
Coal slime after dry and smashing and grinding processing.The coal slime is low ash coal slime or middle grey coal slime.
The application can also provide a kind of moulded coal being made using the moulded coal raw material.
When in use, user weighs a certain amount of raw material to the raw material as needed, and suitable water is added, then by water with
Raw material stirs evenly, and is put into compression moulding in molding die, finally dries the moulded coal of compression moulding.
The application replaces clay used in traditional moulded coal manufacture craft using coal slime, and coal slime provided by the present application, which refers to, washes
The coal slime that coal yard comes out, such as the coal slime of output after the washing coal slime of thermal coal coal washery, coal Hydraulic transportation, this coal slime has
It is all better than raw coal quality, quantity is usually mixed in readymade coal when few.Quantity is more, mixes the only minority fallen, may have a large amount of
High-quality coal slime output.Coal slime can be divided into three classes by the height of ash content and calorific value: low ash coal slime ash content is 20%~32%, heat
Value is 12.5~20MJ/kg;Middle culm plaster is divided into 30%~55%, and calorific value is 8.4~12.5MJ/kg;Dirty coal plaster point >
55%, calorific value is that 3.5~6.3MJ/kg. the application selects low ash coal slime or middle grey coal slime.To guarantee the hair of the moulded coal of production acquisition
Heat reaches design requirement.Since coal slime has many unfavorable conditions such as high-moisture, high viscosity, high retentiveness and low heat value, very
Hardly possible realizes industrial application, and in component provided by the present application, coal slime carries out drying or natural drying processing first, obtains powdered
Then it is carried out hybrid process with coal dust and lime powder or calcium carbide dust by coal slime, coal dust can make up coal slime low heat value
The shortcomings that, simultaneously because coal slime, which meets water, will form high viscosity, therefore some adhesive that can be used as in moulded coal manufacturing process makes
With.
Lime powder or calcium carbide dust provided by the present application, can be used as desulfurizing agent and adhesive uses.Due to coal slime
And lime powder, calcium carbide dust belong to waste, therefore refuse reclamation may be implemented in component provided by the present application, and
The Combustion of Mould Coal effect produced is good, and smokelessly, calory burning is high.The calorific value for the moulded coal that production is formed can achieve traditional
1 times or more of calorific value of coal.
Moulded coal raw material provided by the present application replaces traditional moulded coal to make the clay used using coal slime, is guaranteeing to be made
Moulded coal hardness while reach requirement, the calorific value of moulded coal can be made to greatly promote, while solving current coal slime can not be real
The problem of now recycling industrial production.There is the raw material transport to store characteristic easy to use, is made using the raw material
Moulded coal has many advantages, such as environment protection smokeless, and calorific value is high.
In order to further illustrate scheme provided by the present application, it is described in detail below by specific embodiment:
